Influence of the incorporation of fibers in biscuit dough on proton mobility characterized by time domain NMR
(2016)The effect of fiber addition on the distribution and mobility of protons in biscuits is studied by using low resolution time domain Nuclear Magnetic Resonance (TD-NMR). The proportion of flour is reduced in order to ... -
Multi-characterization of electron-induced defects in highly oriented pyrolytic graphite
(2016)Engineering the properties of materials through defects is at the forefront of research in Materials Science. Here, we investigate the defects produced on highly oriented pyrolytic graphite (HOPG) samples irradiated with ... -
Propiedades de un hilorama clásico
(2016)Un hilorama es una figura formada mediante hilos o cuerdas que unen dos segmentos y se van cruzando entre sí. El efecto visual de estas figuras es llamativo y se utiliza en el arte, el diseño y la arquitectura. En este ... -
Enhancement of dissolution rate of furosemide using a solid dispersion with D-glucosamine HCl
(2016)Furosemide is a potent high ceiling (loop) diuretic mainly used in the treatment of edematous states associated with cardiac, renal, and hepatic failure, and the treatment of hypertension. Furosemide has been classified ... -
Dynamic heterogeneity in the monoclinic phase of CCl4
(2016)Carbon tetrachloride (CCl4) is one of the simplest compounds having a translationally stable monoclinic phase while exhibiting a rich rotational dynamics below 226 K. Recent nuclear quadrupolar resonance (NQR) experiments ... -
Critical exponents and scaling invariance in the absence of a critical point
(2016)The paramagnetic-to-ferromagnetic phase transition is classified as a critical phenomenon due to the power-law behaviour shown by thermodynamic observables when the Curie point is approached. Here we report the observation ... -
La articulación entre saberes matemáticos extraescolares y escolares en el trabajo docente en EDJA
(2016)Esta comunicación se enmarca en un trabajo de investigación sobre la enseñanza de las matemáticas en el nivel primario de la modalidad de jóvenes y adultos. En esta indagación se busca comprender las prácticas docentes y ... -
Interpolation of geometric structures compatible with a pseudo Riemannian metric
(2016)Let (M, g) be a pseudo Riemannian manifold. We consider four geometric structures on M compatible with g: two almost complex and two almost product structures satisfying additionally certain integrability conditions. For ... -
Analytical and rheological studies of modified gel dosimeters exposed to X-ray beams
(2016)The need to know the dose of X-rays to be applied to patients suffering diseases such as cancer requires accurate and stable dosimetric devices. Currently, the use of gelatin-based dosimeters has yielded excellent results ... -
Lie subalgebras of the matrix quantum pseudodifferential operators
(2016)We give a complete description of the anti-involutions that preserve the principal gradation of the algebra of matrix quantum pseudodifferential operators and we describe the Lie subalgebras of their minus fixed points. -
Maximal totally geodesic submanifolds and index of symmetric spaces
(2016)Let M be an irreducible Riemannian symmetric space. The index i(M ) of M is the minimal codimension of a totally geodesic submanifold of M. In [1] we proved that i(M ) is bounded from below by the rank rk(M) of M, that is, ... -
Aportes a la formación del profesorado constructivista : resultados en dos países
(2016)La investigación aborda la influencia que tiene la participación en la investigación educativa en la calidad de la enseñanza de docentes de ciencias experimentales de Argentina y España. Se han utilizado tres vías de acceso ... -
Matrix Gegenbauer polynomials : the 2×2 fundamental cases
(2016)In this paper, we exhibit explicitly a sequence of 2 × 2 matrix valued orthogonal polynomials with respect to a weight W p,n , for any pair of real numbers p and n such that 0 < p < n. The entries of these polynomiales ... -
Center of mass and spin for isolated sources of gravitational radiation
(2016)We define the center of mass and spin of an isolated system in general relativity. The resulting relationships between these variables and the total linear and angular momentum of the gravitational system are remarkably ... -
High resolution, week-long, locomotion time series from Japanese quail in a home-box environment
(2016-06-07)Temporal and spatial patterns of locomotion reflect both resting periods and the movement from one place to another to satisfy physiological and behavioural needs. Locomotion is studied in diverse areas of biology such as ...
